Abstract
this paper provides a Single-Inductor Quadruple-Input-Quadruple-Output buck-boost converter to achieve maximum tracking efficiency of 99.2% due to continuous supply in one cycle. The Maximum Power Point (MPP) tracking mode and the Harvest Energy Delivering (HED) mode harvest each energy harvesting source, deliver energy to the battery and supply it to the loading system in one cycle. Each output voltage ranges from 600mV to 2.5V and the maximum output power is up to 60mW. The peak efficiency is 91.2%.
